Rich, I know you aren't really into apps, (yet) but I thought I'd list some that I think are really good. Going in order by where they are on my phone:
Dark Sky. Warns you ahead of time when it's going to rain. When rain is stopping. Can send you a daily forecast at a set time.
Waze. A route-planning app, but with a whole community, so you know ahead of time if there are hazards along your way- weather, accidents, lanes closed, construction. It's great at picking the fastest route, avoiding traffic, etc., and gives you a choice of three routes. It has saved me countless times from huge traffic jams in Atlanta and Chattanooga.
Hurricane- a really nice hurricane info app.
Lightning Finder- there's an annual subscription, but it shows you real-time lightning strikes near you! I find it fascinating.
Deliveries is the best delivery tracking app I've found.
Spark is the best e-mail app I've found.
(For all these categories, I've tried tens of different apps for each one, and chosen the best.)
Nest lets me monitor and set my Nest thermostat from anywhere. And check the status of my smart smoke detectors.
Map My Run is a great app for running, hiking, walking. Shows you a cool map of your route, and distance, etc.
Yelp is great for finding restaurants while traveling.
There are some really great bird field guides. I use a combination of Merlin Bird ID, iBird Pro and Peterson Birds of NA.
Sky Guide gives you a map of the night sky, as you look at it. Names constellations, etc. wherever you look, at whatever angle- it matches you.
Kindle replaces physical books. Why? Space, for one thing. Portability for another. I have my whole library of books I'm currently reading, everywhere I go, on every device I own. More suited to a tablet, but still nice for a phone.
Audible. Sadly, the internet has stolen virtually all my time I spent reading. But while driving, I love listening to audiobooks.
BugMe! is like pulling out a post-it note for your phone. I use it for jotting down things like a book I want to read, dog body measurements, door codes, just anything I'd write a little note about.
Oh, SplashID is an app that saves info. About everything. Drivers license number. Bank accounts. Credit cards. Log ins. Insurance numbers. Everything. You can back it up to a computer or the cloud. I use it almost daily. Also, I worry about, what if I die? No one is going to be able to even know all the accounts I have, much less access them. SO my solution was, I have a trusted friend (not significant other, not relative) who also has this app. In his app, I created a category called Nanci's SplashID, which has my log-in info. Someone now knows how to access all my vital info if I die accidentally.
